6. Prohibitions and precaution for handling In order to prevent accidents or performance deteriorations in use of the product, observe the following restrictions and pay attentions to the following items.
1) Wave soldering(by solder bath dwelling)is prohibited because this switch does not have a capability. Therefore, be sure to perform soldering by reflow method. 2) Do not put this switch into the washing process after soldering because this switch does not have a capability of washing even water. 6.1 Reflow soldering condition 1) Therefore,be sure to perform soldering by following reflow temperature profile.
2) Three times max.It is possible to conduct reflow soldering with switch side down after at least one time soldering with switch up, but the drop of switch from the PCB and/or flux ingress might happen depend on your manufacturing/soldering condition. So please check if these phenomena do not happen with your manufacturing/soldering process. 3) Please do not load extra heat and pressure during re-work process by iron soldering. In the process of re-work the power of iron solder should be less than 60 W and soldering condition should be as follows, Temperature : 350 ℃ max., Period : 3 seconds max. Time : 1 time only. 4) Do not put any object such as a weight etc. on the operating knob during soldering. 5) In case that this switch is mounted on FPC board like film,we expect the board shall be tough by putting additional board for reinforcement on the reverse side. We are concerned that the switch may be damaged due to an extra stress with multiple undulations from FPC board after soldering. 6.2 Mounting condition 1) As this product is thin and small type,when the mechanical chuck is to be used at automatic mounting, it is subject to be deformed, Please mount after sufficiently ajustment. 6.3 Handing after soldering 1) Do not load extra pressure on the switch after soldering. Example,under the condition like stack of the P.C.bd on the switch. 2) Do not make a extra bending condition of P.C.bd like below figure.
3) In case of using a masking tape on a P.C.db, do not put it on the switch.

6.4 Attentions Required for Unit Design at customer side. 1) When the soldering land pattern is to be designed,design with the recommended land pattern and dimensions described in this Specifications for Information. 2) Design the operationg section on the setting side as shown in the Fig-1. Please design a knob for 1.3 size to be arranged in the direction of the crosspiece.(Refer to the Fig-2) Inclination shall be within 4 degree.(Refer to the Fig-3) The switch and the decentering shall be 0.3 mm max.. For use of this switch,press the center portion,as much as possible however,the life when the switch is pressed deviated from the center is shown below.

6.5 Attentions Required for Other Items 1) Do not apply excessive load on this product.The stopper that shall be put on a button due to protection of this product against excessive load. Pay special attention to the terminal section.It may be a cause of terminal deformation,bad contact, or malfunction. 2) To prevent a bad contact caused by foreign particles (dust particles of P.W.B.,dust,Particles of flux) into the inside of the switch, pay attention to handle the P.W.B. after mounting. And do not pile up the P.W.B.. 3) For storage of this product, avoid the place at high temperature and humidity,and where corrosive gas may be generated. Especially for a long-term storage, do not take out from the package and avoid storing with a loosed condition. 4) Avoid pressing the film portion of the product with sharp-edged object. 5) Please put your attention not to locate big amount of solder paste around the switch, like adding extra land patterns besides the switch, because flux ingress to inside of the switch may occur. 6) This switch is for making a momentary signal. It is prohibited using the switch at a function that expects long time signal (long time contact close). 7) There is a possibility the flux from solder paste infiltrates into the body if plenty of solder paste was applied by switch on the P.W.B. So we recommend to use our proposed land design in order to prevent above problem. Also please avoid putting additional land by the switch on the P.W.B. 6.6 Attentions Required for Circuit Condition 6.6.1 Rating (1) In order to assure the reliability, use this product within the rating range specified in the Specifications. (2) Rated power is a maximum value of the power which can be continuous load at rated ambient temperature. (3) If the product is used over the rated power, the correct characteristics may not be gained or the product may be burnt. (4) The circuit shall be designed to avoid the inrush current to the switch, also avoid the surge voltage to be applied. (5) When the switches is used under a few μA (dry circuit),contact resistance may affect circuit property, so please use the switch under specified switch rating. (6) Do not apply the voltage of rated puncture value min. between the insulation and the electrode. Panasonic Corporation

6.6.2 Attentions Required for Bouncing and Chattering In order to prevent the malfunction by chattering caused by bounching at switch-operation of ON/OFF and external vibration etc., please pay attention to the design shown below. 1) Read several times. 2) Set the delay time. 3) Set the CR integration circuit. 6.7 Attentions Required for Mounting and Operating Condition 6.7.1 Operating temperature In order to assure the reliability, use this product within the operating temperature range specified in the Specifications. 6.7.2 Operating relative humidity Do not use this product under relative humidity of 85% min. for a long time. (Excluding the case that measure is taken in a set.) Avoid using this product in a place where it is directly exposed to the wheather, or where humidity is high caused by steam and dew condensation, etc. 6.7.3 The product is not a sealed type. Avoid the use under following circumstance and conditions as it may affect a bad influence to characteristics. (1) In the corrosive gas atmospere, such as Cl2, H2S, NH3, NOx, SO2 gas. (2) Waterdrop remained, dew condensation, Waterdrop adhered. (3) In the solution of water, sale water, oil, chemicals, and organic solvents. (4) A place where it is exposed to direct sunlight. (5) A place with large amounts of dust or dirt particles. 6.7.4 The structure of this product is not waterproof, chemicals resistance and solvent resistance. Do not wet with water, chemicals and/or solvents. 6.7.5 Do not apply the vibration, the shock (drop, etc.) or the pressure to this product more than specified. 6.7.6 Push strength In order to avoid damages of the switch, do not apply the load to the operating section more than specified.(If the load is applied more than specified, it may affect on the characteristics of the push stroke, etc.) 6.7.7 Avoid the use of the switch under pushed ON condition is continued for a long time. 6.8 Repair･Service 6.8.1 When additional solder to the mounting soldering section of this product is to be performed or soldering section is to be removed, pay attention not to apply excessive stress and the temperature. 6.8.2 Pay attention not to melt the insulation material or the resin section, and avoid deformation.
